Elementary calcium reacts with water. Calcium compounds are more or less water soluble. Calcium carbonate has a solubility of 14 mg/L, which is multiplied by a factor five in presence of carbon dioxide. Calcium phosphate solubility is 20 mg/L, and that of calcium fluoride is 16 mg/L.
Hydroxides in generaldon't dissolve at allBut, barium, strontium and calciumAre slightly soluble The carbonates are insoluble,It's lucky that it is so,Or else, our marble buildingsWould melt away like snow. Alkali metals and ammonium saltsWhatever they may beCan always be depended onFor solubility.lkali metals and ammonium saltsWhatever they may beCan always be depended onFor solubility Every single sulfateIs soluble, 'Tis said'Cept barium, strontium, mercury oneAnd calcium and lead.
